Hello,
I have the 4.11 LSD on my Solex U-20, I really don't think it makes
that much of a difference in around town gass mileage. On the freeway I am
turning maybe 3800rpm at the super fast CA freeway cruising speeds.
But I do think that it makes a difference in low rpm power. The
car really does feel more peppier.
